WINDOW.

SPECIFICATION forming part of Letters Patent No. 555,837, dated March 3, 1896.. Application filed October 25, 1895. Serial No. 566,867. (No model.)

To all whom it may concern:

Beit known that I, FERDINAND G. UnLrcH, a citizen of the United States, and a resident of the city of St. Louis, in the State of Missouri, have invented a certain new and useful Improvement in IVindows, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

My present invention is an improvement in that class of windows in which the panes of glass are held in swinging frames hinged to sash-frames that slide in the window-frame, so that the frames that carry the glass can be opened out into the room to provide easy access to both sides of the glass for cleaning it.

My invention consists in details of construction hereinafter fully described and claimed.

Figure I is a view part in elevation and part in section and illustrative of my invention. Figs. II and III are vertical longitudinal sections taken on line II II, Fig. I, Fig. II showing the sashes in their normal position, while Fig. III shows the inner sash raised and the outer sash lowered. Fig. IV is a detail elevation showing the lower sash partly raised. Fig. V is a detail view with the sash open.

Referring to the drawings, 1 represents the window-frame, which is of ordinary construction.

2 represents the sliding lower sash, and 3 the sliding upper sash. These -fram es are preferably provided with the sash. weight cords et running over the pulleys 5.

6 represents a frame in which the panes of glass 7 of the lower sash are secured. This frame is secured to the sash 2 by means of hinges 8, so as to permit the frame to swing on the sash.

The sash 2 is rectangular in form, consist ing of two vertical strips and two cross-strips, the lower cross-strip, 2, being made narrower than the upper cross-strip, 2b, so as to leave a space between it and the overlapping facing-strip 9 of the sill of the window-frame. The lower strip, 6, of the swinging frame G is formed with an inverted- L-shaped recess and extends clear down to the bottom of the strip 2 of the sash 2, as shown in Fig. II, and laps onto the strip 2, as shown at 10, so that when the sash is in its lower position the strip 6 rests down upon the sill of the windowframe and extends beneath the upper edge of the facing-strip i). There are two objects in thus forming the strip 6LPL and in narrowing the strip 2PL so as to permit of this form of the strip 6a: First, when the sash is in its lower position or when the window is closed it is impossible to open the swinging frame 6, as the strip 6 is held by the overlapping facingstrip 9, and thus entrance through the window from outside is prevented; second, by thus forming the strip 6a so that it extends down to the sill any moisture gathering on the outside of the pane of glass is conducted down between the strip Ga and the strip 2 to the sill and is conducted oft on the inclined surface of the sill, whereas if the strip 6 extended only part way the width of the strip 2L and the lower part of the strip 2a were widened out so as to come up against the facing-strip 9 this moisture would reach the inside of the window-sash and be deposited on top of the facing-strip 9.

IVhen it is desired to clean the lower sash it is raised sufficiently far to bring its lower edge slightly above the top of the facing-strip 9, and then the swinging frame 6 can be opened, as shown in Fig. V.

The pane of glass 11 of the upper sash is held in a swinging frame l2 secured to the upper sash, 3, by means of hinges 13. The lower strip, 14, of the swinging frame 12 is formed with an inverted- L-shaped recess and extends down to the bottom of the lower crosspiece, 15, of the upper sash, 3, so that when the window is closed the swinging frame 12 is held from being opened by the lower crosspiece, 14, of the swinging frame 12 bearing against the upper cross-piece, 2b, of the lower sash, 2, as shown in Fig. II.

When it is desired to clean the outer sash, it is lowered to a point indicated by the dotted line 16, Fig. III, and the inner sash is raised to the position shown in Fig. III, and to permit the inner sash to rise high enough to allow the swinging frame 12 of the outer sash to be opened I form a recess 17 in the transom or top strip of the windowirame, into which the inner sash moves, as shown in Figs. II and III.

I claim as my invention- 1. The combination of a sash formed with a bottom cross-strip of less thickness than the IOO sash, and the swinging frame iitted into the sash, hinged to one side of the sash, and formed with a bottom cross-strip having an inverted- L-shaped recess occupied by the bottom cross-strip of the sash and extending to the bottom of the sash so as to prevent the opening of the swinging frame until the sash is shifted from normal position; substantially as described.

2. The combination of a window-frame having a facing-strip extending upwardly so as swinging frame until the sash is shifted from normal position; substantially as described. 3. The combination of a window frame formed with a recess in the top strip and having a facing-strip extending upwardly so as to overlap the sill, the lower sash adapted to move into said recess, and the upper sash formed with a bottom cross-strip of less thickness than the sash, and the swinging frame fitted into the sash, hinged to one side of the sash, and formed with a bottom cross-strip having an inverted- L-shaped recess occupied by the bottom cross-strip of the sash and eX- tending to the bottom of the sash so as to prevent the opening of the swinging frame until the sash to which it is secured is shifted from normal position; substantially as described.
